Patent number: 8602113Abstract: Provided are coated oil and gas well production devices and methods of making and using such coated devices. In one form, the coated device includes one or more cylindrical bodies, hardbanding on at least a portion of the exposed outer surface, exposed inner surface, or a combination of both exposed outer or inner surface of the one or more cylindrical bodies, and a coating on at least a portion of the inner surface, the outer surface, or a combination thereof of the one or more cylindrical bodies. The coating includes one or more ultra-low friction layers, and one or more buttering layers interposed between the hardbanding and the ultra-low friction coating. The coated oil and gas well production devices may provide for reduced friction, wear, erosion, corrosion, and deposits for well construction, completion and production of oil and gas.Type: GrantFiled: March 30, 2011Date of Patent: December 10, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Hyun Woo Jin, Srinivasan Rajagopalan, Adnan Ozekcin, Tabassumul Haque, Mehmet Deniz Ertas, Bo Zhao, Jeffrey Roberts Bailey, Terris Field Walker
